Abstract: 1,206,729. Nitric acid tail gas purification. ENGELHARD MINERALS & CHEMICALS CORP. 30. Aug., 1968 [1 Sept., 1967], No. 41660/68. Heading C1A. In the process of producing nitric acid which comprises catalytically oxidizing ammonia to oxides of nitrogen and absorbing the oxides of nitrogen in water, the tail gas is purified by reaction in the presence of a precious metal catalyst with a gas containing free hydrogen, which gas is prepared by reacting a hydrocarbon fuel with steam in a reformer heated by the ammonia oxidation product gases. The hydrocarbon may be naphtha, LPG or natural gas, and the precious metal catalyst may be platinum, palladium, rhodium, ruthenium, iridium, osmium or a combination of any two. or more thereof. In the figure, tail gas is heated to 200-600 F. by steam in 8 and by heat exchange with the ammonia oxidation products in 5 and is then passed to purification reactor 10. Steam is generated in 4 from the heat of the ammonia oxidation products and passed to 8 to preheat the tail gas and into reformer 9, which is heated by the ammonia oxidation products and where it reacts with fuel gas/preheated to about 300 F., to form a gas containing hydrogen and carbon monoxide which is passed to purification reactor 10 which is at 200- 600 F. The reformer preferably, employs a catalyst which may be nickel zirconium silicate or nickel aluminium oxide.

Abstract: 1,272,004. Local viewing; X-ray apparatus. MULLARD Ltd. 3 July, 1970 [21 Aug., 1969], No. 41703/69. Headings H4F and H5R. [Also in Division H1] X-ray imaging and display apparatus includes a non-scanning X-ray source, means for switching the source h.t. voltage cyclically through two or more values, a switchable multi-colour image converter and display system capable of changing simultaneously the colour of the whole field of the display, and means for actuating the display colour switching means automatically in synchronism with the source voltage switching means through a corresponding cyclic of two or more colour changes. As described, the arrangement is employed for stereoscopy (Figs. 4, 5 and 6, not shown)-in which two X-ray tubes are employed, alternately energized synchronously with the switching between two colour states of a colour filter or penetron type luminescent screen, which filter or screen is viewed through spectacles having eye-pieces in the form of colour filters for the respective two colours-or for producing and viewing images of a body irradiated in sequence by X-rays of different hardness (Figs. 1, 2 and 3, not shown), for which the X-ray absorption of tissue and of bone is different. The arrangement of Fig. 7 performs both of the above functions: X-ray tubes X1 and X2, which produce overlapping images of the body Z on the screen PI of an image converter, are alternately energized by switch SWx1, which is actuated in synchronism with a switch SWp for causing a member PS to rotate through 90 degrees the plane of polarization of the vertically polarized light from the image converter screen SO produced by passage through a polarization filter Fp, the final image being viewed through spectacles Anp having eyepieces passing horizontally and vertically polarized light, respectively. The image converter includes a phosphor screen PI producing from the incident X-rays a visible or ultra-violet image which is applied via a fibre optic plate FO to the photo-cathode P, whereafter the corresponding electron image is focused upon the output screen SO by the conical anode A. Output screen SO is of penetron type, and is cyclically switched to three different voltages, to produce successive images of three corresponding colours, by a switch SWd, which is actuated in synchronism with a switch SWx2 for switching the X-ray supply voltage through a corresponding three values.

Title: Magnetic digital recorder
IPC: G06K1/12
Filed: 1962-11-05
Abstract: 1,022,783. Digital data storage; feeding magnetic tapes. UNITED GAS CORPORATION. Nov. 5, 1962 [Nov. 15, 1961], No. 41835/62. Addition to 905,050. Headings G4C and G5R. A portable magnetic digital recorder includes a plurality of manually operable decimal switches 10-19, Figs. 1 and 5 (not shown), which are preset to a value which is then recorded on magnetic tape 32 by a recording head 31 having four coils 95-98 for recording decimal digits in binary coded form. Recording is effected by rotating clockwise an operating handle 35 between stops 39, 40, Fig. 5, thereby rotating a clutch plate 42, Fig. 2 (not shown), through 120 degrees so that one of three contactors 38, Fig. 1, moves successively over contacts 73-85, Figs, 1 and 2, thereby recording an initial " 0 " followed by the settings of the switches 10, 19, which are converted to binary coded form in a diode matrix 99-114, a final " end of word " symbol being recorded via the contact 85. If it is noticed that an erroneous setting has been recorded, a button 115, Figs. 1 and 5, is depressed before the corrected word is recorded, thereby causing a special " error " character to be recorded in place of the normal beginning-ofword " 0 to indicate that the preceding erroneous word should be ignored in any subsequent processing of the tape.  Tape feed mechanism. Fig. 6 (not shown).- Rotation of the handle 35 to effect recording drives a shaft 45 to which the clutch plate 42 is screwed, thereby driving a capstan pulley 47 which drives the tape take-up reel 48 via a spring belt 49. A pinch roller 86 keeps the tape in contact with a capstan 46. To prevent any backward rotation of the clutch plate 42 during the return movement of the handle 35, a friction braking pad 54, Fig. 2, is provided to engage its underside. The recorder is a modification of that of the parent Specification from which it differs principally in that the multi-bank digit switches are replaced by single-bank switches and a common diode recording matrix.

Title: Aircraft automatic pilot
IPC: B64C13/24
Filed: 1963-10-24
Abstract: 1,028,866. Automatic steering control. BODENSEEWERK PERKING-ELMER & CO., G.m.b.H. Oct. 24,1963 [Oct. 24,1962], No. 42087/63. Heading G3R. If, in an aircraft electrical automatic pilot, the difference between an attitude error signal and a control surface position feedback signal exceeds a predetermined value, one signal and/or the other is automatically varied to reduce sensitivity and prevent adjustment of the servomotor-operated control surface exceeding a predetermined rate. In Fig. 1 an aircraft is maintained on a desired course by an electrical signal from the pick-off of an azimuth gyro I applied through a power amplifier III to control a rudder servomotor IV. A resistance-condenser network R 3 C introduces a differential component of control and positional negative feedback is applied to the input of amplifier III from a transmitter V. If the input error signal to amplifier III exceeds a predetermined value, indicating the inability of motor IV to follow course deviations e.g. resulting from high speed flight, a pair of Zener diodes VI in the input ciruit of an amplifier VII become conductive so that heating coils W 1 , W 2  are energized to lower the resistance of a thermistor R 1  in shunt with the gyro signal and also lower the resistance of a thermistor R 2  in series with the feedback path. The angle of rudder movement corresponding to a given course deviation is thus decreased to a value which the rudder motor can attain, the smaller rudder deflection being sufficient to correct deviation during high speed flight. The reduction in sensitivity is proportional to the error above the predetermined value at which it becomes  effective, and up to a limit which is determined by a voltage sensitive shunt VIII.
